Found this free giveaway on Twitter today. The giveaway is free foreign currency, the currency being a 1,000 denomination Iraqi Dinar banknote. To get the freebie just have to mention them and their site on social media and e-mail in a screenshot or link as proof. Took me all of about 10 seconds. If you want it you can keep it or you can resell them for probably $2 or $3 on ebay.
